未处理的异常：PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null)

Question

我正在尝试使用颤振应用程序进行谷歌登录，但我收到了这个错误。 我已经获得了 SHA-1 密钥并将其放入 OAuth 和 Firebase，并在 app 目录下设置了 google-services.json 文件。 但我还是遇到了同样的问题。

 E/flutter (12401): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null)

E/flutter (12401): <asynchronous suspension>
E/flutter (12401): 

我是这样设置的。

GCP OAuth

Firebase setting - I filled all blanks

我不知道该区域必须是哪个clientId。

which clientId has to be on this area?

I got 4 clientId because I already used google clientId to make django web login with google

我粘贴了你的代码，但我遇到了同样的问题

Answer 2

第 1 步： 将此依赖项添加到您的 pubsec 文件中

firebase: ^9.0.2
  firebase_core: ^1.2.1
  firebase_database: ^7.1.0
  firebase_auth: ^1.2.0
  font_awesome_flutter: ^9.0.0
  google_sign_in: ^5.0.3

步骤：2 创建一个新的 dart 文件并粘贴此代码

import 'package:firebase_auth/firebase_auth.dart';
import 'package:google_sign_in/google_sign_in.dart';

class FirebaseService {
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final GoogleSignIn _googleSignIn = GoogleSignIn();

  Future<String?> signInwithGoogle() async {
    try {
      final GoogleSignInAccount? googleSignInAccount =
          await _googleSignIn.signIn();
      final GoogleSignInAuthentication googleSignInAuthentication =
          await googleSignInAccount!.authentication;
      final AuthCredential credential = GoogleAuthProvider.credential(
        accessToken: googleSignInAuthentication.accessToken,
        idToken: googleSignInAuthentication.idToken,
      );
      await _auth.signInWithCredential(credential);
    } on FirebaseAuthException catch (e) {
      print(e.message);
      throw e;
    }
  }

  Future<void> signOutFromGoogle() async{
    await _googleSignIn.signOut();
    await _auth.signOut();
  }
}

第 3 步： 使用谷歌功能调用登录：

在 Firebase 中启用 Google 登录 将您的 SHA 1 密钥添加到 Firebase 项目中
